Ground issues 1974 F100
Just purchased this project truck, noticed when the head lights are on, blinkers working, or brake is pushed, the temperature gauge moves to hot and fuel gauge moves to full, also when the dash lights are on the indicator turn signal lights in the dash light up but are dim compared to when the lights are not on. I am pretty sure it is a ground issue and was wandering if anyone else has seen this proble to direct me where to go to find it? Thank you.

You're on the right track. Make sure there's a healthy ground strap from the firewall to the engine block, and that it bolts to both places on clean, unpainted, rust-free metal. Welcome to FTE by the way!
